Mine was the both vans, the 250 not strong but, works, & 650 had problems with pumps & varicontrollers. Took it back & replaced varicontrollers. Now working very well. For the money they arnt bad. But, you gets what you pay for, i personally prefer Tucker over Ionics, & we are still using a 03 Tucker with out problems, min 5 days a week.
Cheers
